Astronomers have found a galaxy whose super-luminous nucleus–called a quasar–is burning 100 times as much energy as the entire Milky Way galaxy.

Though theory has long predicted that quasars this powerful should exist, the newly-discovered object, known as SDSS J1106+1939, is by far the most energetic ever observed. The quasar is powered by a supermassive black hole that lies at its center.
